description | PROBLEM TO BE SOLVED: To provide a method for manufacturing calcium carbonate being a fine particle, difficult to coagulate and excellent in preservation stability with industrial advantages. SOLUTION: Calcium carbonate is produced by carbonating calcium hydroxide in an aqueous suspension of calcium hydroxide by using introduced gaseous carbon dioxide. Polycarboxylic acid or its ammonium salt is added to the aqueous suspension after starting the introduction of gaseous carbon dioxide. COPYRIGHT: (C)2005,JPO&NCIPI |
